At DMG Motorsports, we present the RK Excel 525XRE Drive Chain (525 x 130 links, part number 525XRE-130) — a high-performance sealed motorcycle chain built for riders who demand smooth power delivery and long-term durability. As the successor to RK's respected XSO line, the XRE series brings advanced sealing technology and a stronger, lighter design to street and off-road machines alike. Whether you're replacing a worn OE chain or upgrading for spirited riding, this 525-pitch chain delivers the balance of strength, low weight, and wear resistance that serious riders expect from RK Excel.

Features:

• RK's original double-X-shaped "XW-Ring" seal design, providing three lubricant pools for exceptionally long chain wear-life compared to conventional O-rings
• Successor to the XSO series, engineered to deliver a 20% longer wear-life while protecting against high-speed abrasion and dirt/debris intrusion into the rollers and bushings
• Lubricated with specially formulated, vacuum-injected U-grease locked in by tough Nitrile Butadine rubber XW-Rings for consistent performance in demanding conditions
• Polished and shot-peened link plates for reduced weight, smooth operation, and quick acceleration
• Rated tensile strength of 9,400 lbs, supporting up to 1000cc street and off-road applications and 200 max horsepower
• Compact 22.5mm max chain width at approximately 3.97 lbs, offering broad compatibility without sacrificing strength
• 130-link length (525 pitch) with a rivet-style masterlink included for secure, permanent installation
• Ideal for OE replacement or performance upgrade on mid-size to large displacement motorcycles
